TL;DR

The module doesn't sufficiently sanitize API response messages before rendering them in HTML output. The _cleantalk_die() and ct_die() functions output the CleanTalk API response message directly into HTML without proper sanitization, allowing potential injection of arbitrary HTML or JavaScript.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
